Trolley-wire hanger

EDWARD HEYDON, or INDIANAPOLIS, INDIANA.

' TROLLEY-WIRE HANGER.

To all whom it may concern: I

Be it known that I, EDWARD HEYDON,- a

citizen of the United States, residing at In? dianapolis, in the county of Marion and State of Indiana, have invented a new and parts thereon and also by the action of the supporting cross-wire so that the two parts will be held together even though the crosswire breaks.

- The accompanying drawing illustrates my invention. Figure 1 1s a plan of my meproved trolley-wire hanger, partly in section on the line l-l of Fig. 2; Fig. 2 is a side elevation of such trolley-wire hanger; Fig. 3 is a plan of the body of the hanger; and Fig. 4 is an elevation of the end of the yoke.

The hanger body 10 has suitably mounted in it a screw stud 11, which is insulated from the hanger body by suitable insulation 12, shown in section in Fig. 1. Any suitable trolley ear 13 is mounted on the screw stud 11. The hanger body 10 is in general bellshaped, but is provided near the top with a circumferential groove 14, by which it is supported. On the top the body 10 is provided with four lugs 15, arranged to provide two cross slots 16 for receiving any suitable tool for turning the body in its support.

The body 10 is supported in a yoke 20, which is provided at its middle with a laterally opening recess 21 by which it interfits in the groove 14 of the body 10. The opening 21 is initially U-shaped, of proper size to permit the insertion of the body 10; and the depth of the U is greater than the radius of the body 10 at the groove 14, and when such body is in place the projecting fingers 22 at the ends of the U-shaped recess 21 are hammered inward as shown in Fig. 1 to lock the body and yoke together. The yoke also has two opposite projecting arms 23, each of which is provided at its end with a horizontal slot 24 opening toward the opposite side of the yoke from that toward which the recess 21 opens. These slots 24 receive the supporting cross-wire 25, which is under tension in the usual manner and which between the projecting arms 23 lies in the groove 14 Specification of Letters Patent.

ofthe body 10 on the Patented Apr. 19, 1e21,

opposite side thereof from the yoke. In other words, the cross wire 25 passes around the body 10 011 the oppositeside thereof fromthat toward which theslots 24 open. In consequence, the tension of the cross-wire 25 forces'the body 10 into the opening 21, and holds such crosswire firmly in the slots 24. Yet if the crosswire 25 breaks, the fingers 22 hold the body 10 and yoke 20 together. In addition, the tension of the cross-wire 25 efiectively locks the body 10 againstturning in the yoke 20, thus preventing the screw stud 11 from working loose from the trolley ear, 13. Yet when desired the body 10 may be turned in the yoke 20, by a suitable tool inserted in one of theslots 16,. to permit the angular relationship betweenthe yoke 20 and the trolleywire in the ear 13 to be adjusted as desired; The body and the yoke may be attached together either in the shop or by the lineman when he is installing the hanger; and if it is necessary for any reason to separate them this can be done readily by bending out the fingers 22.

I claim as my invention:

1. A trolley-wire hanger, comprising a body having a circumferential groove, and a yoke having a laterally opening recess arranged to receive the body by interfitting with said groove, said yoke having at the sides of said recess projecting fingers which can be bent toward each other to lock the body and yoke together.

2. A trolley-wire hanger, comprising a body having a circumferential groove, a yoke having a laterally opening recess for receiving said body and interfitting with the groove and also having two opposite projecting arms for engaging a cross-wire, the opening of said recess being transverse to the line of said projecting arms so that a cross-wire passing between them and around the groove in the body portion on the open side of the said recess will lock the body and yoke together, and means additional to said cross-Wire for locking said body and yoke together.

3. A trolley-wire hanger, comprising a body having a circumferential groove, a yoke having a laterally opening recess for receiving said body; by interfitting with said groove, said yoke being provided with a bendable finger which can be bent into said groove to hold the body and yoke together.

4. A trolley-wire hanger, comprising a body having a circumferential groove, a yoke having a laterally opening recess for receiving said body by interfitting; with said groove, said yoke being provided withm a bendable finger which can be'bent into said groove to hold the body and yoke together, and said body being rotatable in said yoke and being provided with upwardly projecting lugs which form a slot for the reception of a tool foryproducing such rotation. v

5. A trolley-wire hanger, comprising a body and a yoke separate from each other, said body'being mounted in said yoke, and said body and :yoke being arranged so that they are heldtogether by the tension of a supporting crossswire, and additional means for holdingthe body and'yoke together.

6. A trolley-wire "hanger, comprising a body and a-yoke separate fromeachother, said body being'mounted in: said yoke, and said body and yoke being arranged so that they are. held together by the tension of a supporting cross-wire, and additional means for holding the body andyoke together, the mounting of said bodyin said yoke permitting relative rotation between them, and the body being provided with a slot for receiving a tool for producing such rotation.

7. A trolley-wire hanger, comprising a body having a circumferential groove, a

yoke having a laterally opening recess for receiving said body. and interfitting with the groove and also having two opposite projecting-arms for engaging a cross-wire, the opening of said recess being transverse tothe line of said projecting arms so that a cross-wire passing between them and around the'groove-in the bodyportion on the open body and ayokeseparate from each other,

said body being mounted insaid yoke, and

said body and yoke being arranged so that they are held together by the tension of a V supporting cross-wire, the mounting of said bodyin said yoke permitting relative rotation between them, and the .body being pro vided with a slot for receiving tool for producing such rotation. p

In witness whereof,I"have hereunto set my hand at Indianapolis, Indiana, this 20th day of November, D. one. thousand nine hundred and nineteen.

EDWARD HEYDON.
